E-business refers to connecting business operations electronically to customers, suppliers, employees and partners. This is broader than just e-commerce and includes customer service, collaboration and processing transactions. E-business evolved from electronic data interchange in the 1970s to widespread internet use in the 1990s and 2000s, shifting focus from B2C to B2B to additional areas like education and mobile commerce. E-business allows for reduced costs, global reach, convenience and higher productivity compared to traditional offline business.
